And that is measured as a macroscopic crosssection of absorption thermal divided by the integral of all energies in terms of absorptions.
那是被测量的,作为吸收热能的,宏观横截面,除以全部的,吸收的能量的乘积。

We can then look at uranium 238 which has a relatively low absorption thermal energy range and essentially has no fission crosssection which is why we call uranium 238 a fertile atom.
The rotating irradiation model for ND silicon presented in this paper gives distribution, mean value and heterogeneity of the thermal flux on the crosssection of silicon.
